The Inside Story of Polarized Lenses

Polarized lenses are regular sunglass lenses with an additional polarization layer fused to the lens.

How Polarized sunglass lenses are made and how polarized sunglass lenses work to combat Australia's powerful Sunglare

All of our sunglass lenses eliminate almost all UV Rays. Regular sunglass lenses reduce glare by blocking visible light in an equal manner across the entire lens. Polarized lenses, on the other hand, act like millions of microscopic mirrors that are angled away from your eyes field of vision. When light waves hit the polarization layer at various angles that are not perpendicular to your lens it's reflected away rather than let through to your eye. This results in unwanted glare from roads, water and car windows being either dulled out or seriously reduced allowing you to see the field of vision the way you want.

The reduction of glare provided by sunglass lenses allows you to wear your sunglasses for much longer periods of time with reduced eyestrain and squinting eyes. We also have customers that suffer from migraines who claim that polarized lenses help reduce the onset of headaches.

With free Australian and worldwide shipping along with easy to follow video instructions to help you replace your sunglass lenses with new polarized lenses, it's never been easier to upgrade for the best quality lenses your eyes deserve, especially with the harsh UV Sun Rays in Australia.

When Polarized Lenses Can Cause Problems?

Because polarized lenses block out glare and light at certain angles it can prevent you from seeing reflections you'd normally see. Any reflection off wet patches on the road or your favourite ski slopes may not show up as strong as normal. Also, LCD displays from certain devices such as car stereos, microwaves, mobile and computer monitors may not get blocked out, especially with lower quality polarization films. We've had feedback from customers about the polarization interacting with polarized films in their tinted car windows.

How do I know if I have Polarized Lenses?

If your lenses are removed from your sunglasses, turn one lens 90 degrees from the other and look through both lenses at the same time. You will notice that you can't see out of the lenses. Regular sunglass lenses will just appear darker and maintain the same level of tint as they are turned. If you lenses are still in your sunglasses you can look at a high glare reflection off a car window. If you turn your sunglasses in a clockwise motion while looking at the glare it will get brighter and duller as the sunglasses are turned if the lenses are polarized. If the glare remains the same, you have regular sunglass lenses.

If you turn one polarized lens perpendicular to another (90 degrees) the films block all visible light as they both work to block light waves from different angles. Polarized lenses block out entire view when turned 90 degree from each other as the films interact to block all visible light.
If two polarized lenses are looked through while they are parallel to each other you can see through them like regular lenses. The view is just darker. When looking through polarized lenses in parallel they look like regular lenses. They show the view but just darker.
